Answer:

X=7

take the -21 to the other side of the equation, when you do this it goes from a negative to a positive so we now have 63+21=12x

if we add 63 and 12 we get 84 decide by 12 because we have 12x and we get 7

Question 1 of 10
Darya [45]

Answer:

Log₆ (A⁵C² / D⁶) = –13

Step-by-step explanation:

From the question given above,

Log₆ A = 1

Log₆ C = 3

Log₆ D = 4

Log₆ (A⁵C² / D⁶) =?

Recall:

Log MN / U = Log M + Log N – Log U

Therefore,

Log₆ (A⁵C² / D⁶) = Log₆ A⁵ + Log₆ C² – Log₆ D⁶

Recall:

Log Mⁿ = nLog M

Thus,

Log₆ A⁵ + Log₆ C² – Log₆ D⁶

= 5Log₆ A + 2Log₆ C – 6Log₆ D

Log₆ A = 1

Log₆ C = 3

Log₆ D = 4

= 5(1) + 2(3) – 6(4)

= 5 + 6 – 24

= 11 – 24

= –13

Therefore,

Log₆ (A⁵C² / D⁶) = –13

Step-by-step explanation:

4/5 =0.8

1/4=0.25

  ⇒0.8 - 0.25 = 0.55 (decimal form)

  ⇒4/5 - 1/4 = 11/20 (exact form-fraction)
